Description

[Technical Field]

[0001] The present invention relates to a fragrance accord, the use of the fragrance accord to enhance the bloom linearity of a fragrance composition, and a method for enhancing the bloom linearity of a fragrance composition. [Background technology]

[0002] One sought-after benefit of fragranced products is the production of a pleasant odor that enhances user comfort and leads to olfactory cues related to product effectiveness. In fabric laundering, this has traditionally translated into the production of a strong blooming odor on wet fabrics, combined with a long-lasting odor on dry fabrics. Both blooming and long-lasting odors have the added benefit of signaling the freshness and cleanliness of freshly washed fabrics. However, today, consumers are increasingly eager to experience improved returns from fragranced products. The ability of consumer products to produce an odor that fills the room in which the product is applied is becoming a key performance indicator that regulates product repurchase. In fabric care, room filling enhances the action of fragranced products during the line-drying stage, reinforcing the perception of cleanliness and hygiene in the room in which the fabrics are dried.

[0003] In particular, it is highly desirable that the room fill during line drying be perceived by the consumer as a continuation of the fresh, clean impression experienced upon removing the laundry from the washing machine. In other words, it is highly desirable that fragrance compositions employed to perfume fabric care products be able to provide an "extended" (or "linear") bloom that preferably lasts as long as the fabric remains wet.

[0004] U.S. Patent No. 9,885,009 discloses a fabric conditioning composition containing a mixture of microcapsules with different release profiles that significantly increase scent perception during multiple stages of the laundry process. The microcapsules differ in properties because their polymer walls are made using the same polymer but different curing temperatures, curing times, or a combination thereof. Such an approach requires the use of microcapsules to achieve the desired scent perception profile.

[0005] WO 2018 / 071897 A1 discloses a high-performance, high-impact bloom accord containing fragrance ingredients with a predefined diffusion rate. The diffusion rate is calculated as the distance traveled by the fragrance divided by the so-called diffusion rate. However, the disclosed compositional rules are not intended to produce linear bloom in fabrics.

[0006] Creating such linear fragrance bloom is difficult. Commercially available products typically provide a strong bloom that is perceived on wet fabrics removed from the washing machine at the expense of room fill during the drying stage, or vice versa. Meanwhile, attempts to provide an optimal balance between bloom and room fill typically result in diminished effectiveness of both.

[0007] Furthermore, for consumers to perceive bloom linearity, the fragrance intensity perceived during the dry stage should preferably be higher than the intensity perceived upon removal from the machine. Under these conditions, consumers are less susceptible to fatigue and habituation that may otherwise occur under real-life conditions.

[0008] It is therefore the object underlying the present invention to address the above-mentioned shortcomings in the prior art, and in particular to provide a fragrance composition for fabric care products that provides a linear bloom that begins the moment the fabric is removed from the washing machine, is perceived as room filling during the line drying stage, and is hedonically pleasant to the consumer throughout the perceived time the product is applied.

[0009] This problem is solved by the subject matter of the independent claims. In a first aspect, the invention comprises: a) Group A fragrance ingredients, such as 2-cyclohexylidene-2-phenylacetonitrile (Peonile™); 2-cyclohexylidene-2-(o-tolyl)acetonitrile (Petalia); (E)-3,7-dimethylnona-1,6-dien-3-ol (Ethyl Linalool); 3-(4-(tert-butyl)phenyl)-2-methylpropanal (Lilial); 3-(4-(2-methylpropyl)-2-methylphenyl)-propanal (Nympheal); 3-methylbut-2-en-1-yl acetate (Prenyl Acetate; 1-(2,3,8,8-tetramethyl-1,2,3,4,5,6,7,8-octahydronaphthalen-2-yl)ethanone (Sylvamber); (E)-4-methyldec-3-en-5-ol (Undecavertol); (1s,4s)-1,3,3-trimethyl-2-oxabicyclo[2.2.2]octane (Eucalyptol); (4Z)-hept-4-en-2-yl 2-hydroxybenzoate (Karmaflor); 6-methoxy-2,6-dimethyloctanal (Calypsone); 70 to 92% by weight, preferably 85 to 91% by weight, of at least two fragrance ingredients selected from the group consisting of Eucalyptus Globulus Oil and Patchouli Oil;

[0010] b) Group B fragrance ingredients include 4-methyl-2-phenyl-3,6-dihydro-2H-pyran (Rosyrane); (Z)-hex-3-en-1-yl methyl carbonate (Liffarome); 2-methoxynaphthalene (Yara Yara); 1-methyl-2-(5-methylhex-4-en-2-yl)cyclopropylmethanol (Rosyfolia); 1-(2,6,6-trimethyl-1-cyclohex-3-enyl)but-2-en-1-one (Damascone Delta); methyl 2,4-dihydroxy-3,6-dimethylbenzoate (Evernyl); and 3-ethoxy-4-hydroxybenzaldehyde (Ethyl Vanillin; 2,2,2-trichloro-1-phenylethyl acetate (Rosacetol); (Z)-3-methylcyclotetradec-5-enone (Cosmone); 1,3,4,5,6,7-hexahydro-β-1,1,5,5-pentamethyl-2H-2,4a-methanonaphthalene-8-ethanol (Ambermax); 2-ethoxy-4-(methoxymethyl)phenol (Methyl 5 to 29.5% by weight, preferably 8 to 12% by weight, of at least two fragrance ingredients selected from the group consisting of Diantilis; 1-methyl-2-((1,2,2-trimethylbicyclo[3.1.0]hexan-3-yl)methyl)cyclopropyl)methanol (Javanol); (E)-2-ethyl-4-(2,2,3-trimethylcyclopent-3-en-1-yl)but-2-en-1-ol (Radjanol)) and (2E,5E)-5,6,7-trimethylocta-2,5-dien-4-one (Pomarose); and

[0011] c) Group C fragrance ingredients include decahydro-2,2,6,6,7,8,8-heptamethylindenofuran (Amber Xtrem); (2-methoxyethyl)benzene (Pandanol); 2-methyl-4-propyl-1,3-oxathiane (Oxane); 2-(2,4-dimethylcyclohexyl)pyridine (Zinarine); ethyl cyclohexylcarboxylate (Esterly); and (2E,6Z)-nona-2,6-dienenitrile (Violet 0.5 to 3% by weight, preferably 0.9 to 1.5% by weight, of at least one fragrance ingredient selected from the group consisting of Nitrile; (E)-Decenal-4-Trans; (Z)-Decenal-4-Cis; (Z)-Non-6-Cis; 5-tert-butyl-2-methyl-5-propyl-2H-furan (Cassyrane); 1-(5,5-dimethylcyclohex-1-en-1-yl)pent-4-en-1-one (Galbanone Pure); 1-Methoxy-7,9-dimethyl-2-oxaspiro[5.5]undec-8-ene (Ebelia); 2,4-dimethyl-4-phenyltetrahydrofuran (Rhubafuran) and 2,4,7-trimethyloct-6-en-1-ol (Pomelol); The present invention provides a fragrance accord consisting of:

[0012] When added to consumer products, especially laundry care products, fragrance accords that meet the aforementioned compositional rules exhibit enhanced bloom intensity and room-filling intensity, as well as an optimal balance between these two effects.

[0013] In the context of the present invention, bloom intensity is assessed immediately upon opening the washing machine window at a distance of 0.5 to 2 meters from the window.

[0014] Indoor fill strength is assessed at a distance of 0.5 to 2 metres from the line after the fabric has been line dried for a specific period of time, say between 15 and 60 minutes.

[0015] Preferably, both bloom strength and room-fill strength are evaluated according to a standardized procedure as described below in Example 3 herein.

[0016] More specifically, the fragrances of the present invention improve the bloom linearity of fragrances on fabrics. This means that not only are the perceived bloom and room fill intensities enhanced, but the perceived difference between these two intensities is maintained and even increased. Under these circumstances, consumers do not experience fatigue or habituation, as occurs with conventional products. Such benefits are surprising because they cannot be directly inferred from the vapor pressure, odor detection threshold, or odor value (OV) (i.e., the ratio of volatility or equilibrium headspace concentration to odor detection threshold) of the selected ingredients. Thus, for example, Galaxolide™ and Peonile have volatilities of 1-2 μg / L at 25°C, and both have logOV values ​​of 3.6. However, Peonile was found to outperform Galaxolide by 7.6 times in bloom intensity and 5.2 times in room fill. Similarly, Rosilan was found to have slightly higher volatility (170 μg / l) than methyl anthranilate (100 μg / l) at 25°C, and while both have similar logOVs of 6.2 and 5.9, respectively, Rosilan performed seven times and three times the bloom strength of methyl anthranilate. Similarly, citronellol and undecavertol have similar volatilities of 130 μg / l and 145 μg / l, with logOVs of 4.4 and 4.5, but undecavertol performed four times and twice as well as citronellol in bloom strength and indoor filling, respectively.

[0017] The term "volatility" refers to the equilibrium headspace concentration (HS), expressed in micrograms per liter (μg / l). This is the concentration of a component in the gas phase in equilibrium with its condensed form, i.e., solid or liquid form, at a temperature of 25° C. and a pressure of 1 atmosphere (normal pressure). It can be measured using any of the quantitative headspace analysis techniques known in the art. Suitable methods are described, for example, by Mueller and Lamparsky in Perfumes: Art, Science and Technology, Chapter 6 "The Measurement of Odors" (pp. 176-179 (Elsevier 1991)).

[0018] Equilibrium headspace concentrations can be measured as follows: 500 mg of the test fragrance ingredient is added to a container, which is then sealed. The container is incubated at a constant temperature of 25°C until the compound reaches equilibrium between the gas and condensed phases. A defined volume of headspace (typically 0.5–1.0 L) is trapped in a microfilter using a poly(4-ethylstyrene-co-divinylbenzene) porous material, such as Porapak Q from Supelco, as a sorbent. After extraction with an appropriate solvent (typically 30–100 μL of methyl tertiary butyl ether), an aliquot of the extract is analyzed by gas chromatography. The original headspace concentration (in μg / L) can be calculated from the headspace volume aspirated through the microfilter and the aliquot of the filtered extract injected into the gas chromatograph. The final headspace concentration value for each tested fragrance ingredient is obtained as the average of three independent measurements. Further information on the techniques described herein can be found in the article by Etzweiler, F.; Senn E. and Neuner-Jehle N., Ber. Bunsen-Ges. Phys. Chem. 1984, 88, 578-583.

[0019] The term "odor detection threshold" (ODT) as used herein above refers to the average concentration above which a fragrance component can be detected by a panelist and measured by olfactometry, as described, for example, by Mueller and Lamparsky in Perfumes: Art, Science and Technology, Chapter 6 "The Measurement of Odors" (Elsevier 1991).

[0020] The odor detection threshold (ODT) may be measured using an olfactometer. Olfactometers work based on the principle of linear dilution of odorants in a carrier gas. The amount of odorant displaced depends on its vapor pressure and the carrier gas flow rate. A constant nitrogen flow, regulated by a flow regulator, transports the odorant from the sample container to a mixing chamber. There, the carrier gas-odor mixture is diluted with odorless air. A portion of the diluted odorous air from the mixing chamber flows into a sniffing funnel via a fused silica capillary. The flow rate through the capillary, which determines the dosage of odorous air from the mixing chamber to the sniffing funnel, depends on the opening of a valve that can be adjusted via a PC from 1 to 256 mL in binary steps. Final dilution of the odor sample is performed in a glass funnel by thoroughly flushing it with odorless air at a flow rate of 8 L / min. Forced-choice triangle presentation is achieved by a special automated channel setting device in which only one position of the switch allows the odorant-delivering capillary to enter the sniffing funnel, while the other two positions place the capillary outside the funnel and wick away the outflow. After each trial, the channel setting is automatically changed in a random order. Concentration is calculated from the odorant vapor pressure and the dilution ratio applied to the olfactometer, assuming vapor pressure saturation is achieved in the sample generator. As a control, concentration is analytically determined by sampling a known volume from the capillary effluent onto a headspace filter, followed by gas chromatographic quantification of the odorant in the desorption solution.

[0021] Each panelist (15 people) begins sniffing the olfactometer at a concentration level that allows them to perceive the odorant at a moderate intensity. After three correct responses in three consecutive trials (or four correct responses in five trials) at the same level, the stimulus concentration is reduced two-fold to the next lower level until the panelist reaches their individual threshold level. The final threshold for a given odorant is obtained as the average of all individual threshold levels.

[0022] The aforementioned ingredients may be combined by a skilled perfumer to achieve the appropriate hedonic effect, such as the desired odor direction and pleasure.

[0079] Specific features and further advantages of the present invention will become apparent from the following examples.

[0080] Example 1: Fragrance Accords According to the Invention The fragrance accords in Table 1 were prepared by mixing the corresponding fragrance ingredients. [Table 1]

[0081] Example 2: Fragrance Composition A first series of fragrance compositions was prepared by mixing 10% by weight of the fragrance accord described in Example 1 with 90% by weight of other ingredients different from those present in the fragrance. No fragrance was added to Example 2.0, which served as a reference. These fragrance compositions are shown in Table 2.

[0082] [Table 2-1] [Table 2-2]

[0083] A second series of compositions was prepared in which the other fragrance ingredients were replaced with reference fragrances A, B and C selected from proprietary conventional laundry detergent care fragrances (e.g. Givaudan). Fragrance compositions were prepared by mixing various levels of the reference fragrance of Example 1 and the fragrances of 1.4 and 1.5. Examples 2.7, 2.9, 2.10, 2.12, 2.13, 2.15 and 2.16 are fragrance compositions according to the invention, while Examples 2.6, 2.8, 2.11 and 2.14 are comparative examples. [Table 3]

[0084] Example 3: Cleaning and Olfactory Assessment Procedure The fragrances in Tables 2 and 3 were mixed with standard unscented liquid laundry care detergent at levels of 0.32 wt% for Examples 2.1-2.16 and 2.1-2.5, 0.69 wt% for Examples 2.6-2.13, and 0.42 wt% for Examples 2.14-2.16. The mixtures were allowed to soak for three days before further use. 35 ml of this detergent was used in a European-style front-loading washing machine loaded with 1.2 kg of cotton fabric, consisting of three shirts, two coarse towels, and two large bed sheets. The wash cycle was completed at 40°C for 50 minutes, followed by spin drying at 1000 rpm. " Outside the machineFor the " rating, the machine was tested at 10 m with an airflow of 25 air changes per hour. 3 Panelists were instructed to enter the booth in pairs, with one panelist instructed to open the machine door. Panelists faced away from the booth door, and odor intensity in this position was rated the moment the odor was first detected. " Indoor filling For strength evaluation, the washed fabrics were immediately transferred to a line drying setup located within the booth. The air exchange was stopped and the fabrics were allowed to dry for 30 minutes. Panelists were instructed to make their evaluations through the portholes in the booth. For Examples 2.0 to 2.5, an olfactory evaluation was performed by a panel of five expert panelists. Odor intensity was scored on a scale of 1 to 5 (1 = barely noticeable, 2 = weak, 3 = moderate, 4 = strong, 5 = very strong). At the same time, a qualitative description of the odor was recorded. These results are reported in Table 4.

[0085] [Table 4]

[0086] As can be seen from Table 4, adding a fragrance accord according to the invention increases both the odor intensity both off-machine and in the drying stage compared to Reference 2.0, but also adds positive attributes to the odor quality. For Examples 2.6-2.16, olfactory evaluations were conducted by a panel of 25 trained lay panelists. The evaluation protocol was the same as that described above for Examples 2.0-2.5, except that odor intensity was scored on a 100-unit scale for both "out of machine" and "room-filled" evaluations. The results are reported in Table 5. Here, the "bloom linearity improvement" factor is defined as the difference between the perceived intensity during line drying and when the machine is open. [Table 5] As can be seen from Table 5, the addition of a blooming accord according to the invention on top of a conventional (reference) fragrance significantly enhances both the bloom odor intensity upon machine opening and during line drying. Furthermore, the bloom linearity of the new fragrance compositions is maintained (Example 2.2 vs. Reference 2.1) or even enhanced (see Examples 2.4 and 2.5 vs. Reference 2.3, Examples 2.7 and 2.8 vs. Control 2.6, and Examples 2.10 and 2.11 vs. Reference 2.9).
